Know God as He Has Revealed Himself
A seminary-grade study of Theology Proper — God's nature, attributes, and triune being — grounded in Scripture, sharpened by the historic Christian tradition, and built for learners who refuse to stay in the shallows.
The doctrine of God is not a gateway you pass through — it is the ground you never stop standing on, and it deserves the most careful thinking you can bring to it.

What you'll learn
What you'll be able to do
- Articulate a comprehensive biblical account of God's nature, character, and works drawn from both Old and New Testament revelation
- Explain the doctrine of the Trinity — including the biblical witness to the Father, Son, and Holy Spirit — and trace how the early Church formulated Trinitarian theology through the ecumenical creeds
- Define and distinguish the classical divine attributes (aseity, immutability, omniscience, holiness, love, and more) and explain how they form a unified portrait of God's perfect being
- Evaluate major theological controversies — including debates over divine simplicity, impassibility, timelessness, and foreknowledge — using Scripture and the historic Christian tradition as your guide
- Engage the contributions of key theologians from Augustine and Aquinas to Barth and contemporary evangelical scholars, situating their work within the broader development of Christian doctrine
- Construct a coherent, well-grounded doctrine of God that informs biblical interpretation, theological discernment, faithful worship, and Christian discipleship

Who it's for
Is this you?
Seminary students
Seeking a course that matches the rigor of their formal studies while giving them structured, independent access to Theology Proper's full scope.
Pastors and preachers
Wanting a doctrinally deep, pastorally grounded foundation so that their preaching and shepherding rest on a rightly ordered vision of who God is.
Lay theologians
Committed church members who read widely and think carefully, ready to engage the classical attributes and Trinitarian theology at a serious academic level.
Bible study leaders
Preparing to guide others well means knowing the doctrine of God deeply — including how God's attributes, names, and triune being are actually taught in Scripture.
Theology graduates revisiting the foundations
Returning to Theology Proper with fresh eyes — and to the hard questions about impassibility, foreknowledge, and divine simplicity they want to think through more carefully.
Devout independent learners
Christians without formal theological training who are hungry for substantive, Scripture-rooted answers to the deepest questions about the nature and character of God.

A note from your teacher
Theoria
Perhaps you have been in ministry or in serious Bible study for some time, and you have felt a growing sense that the doctrine of God — the very first and most foundational question of Christian theology — deserves far more careful attention than most of us gave it early on. You love Scripture. You believe it is authoritative. But when a question comes up about divine timelessness, or whether God can suffer, or what the Nicene Creed actually commits you to, you find yourself wishing you had a more rigorous framework — something more than memory verses and popular-level books, however good those may be.
That is precisely why this course exists.
What you will find here is the kind of theological education that used to require a seminary library and a patient professor — now structured for the serious learner who can work at their own pace but refuses to work at a shallow depth. We begin at the foundation: What is Theology Proper, and how do we do it faithfully? That question of theological method matters enormously, because how you reason about God shapes everything you conclude about Him. We move from there through the biblical revelation of God — His names, His self-disclosure in redemptive history, His witness in the New Testament — before entering the great doctrinal territory of the Trinity and the divine attributes.
I want to be honest with you about what this course asks of you: genuine intellectual engagement. The questions we are handling — divine aseity, simplicity, impassibility, the foreknowledge debates, the grammar of Trinitarian relations — are questions the Church's finest minds have wrestled with for centuries. We will not pretend they are easy. But neither will we treat them as inaccessible. Every concept is explained. Every controversy is mapped with care. Every hard question is an invitation to think more precisely about an infinitely worthy subject.
What I hope you will carry away is not merely a longer list of theological propositions, but a transformed way of thinking about God — one that is accountable to Scripture, tutored by the best of the Christian tradition, and genuinely useful for worship, preaching, biblical interpretation, and the daily life of faith. The doctrine of God is not a prerequisite you get past on your way to more interesting theology. It is the ground on which every other doctrine stands.
I am glad you are here. Let's do this work together — carefully, reverently, and without hurrying past anything that deserves our full attention.
